Example 2
This example is a base case for exploring the effects of operating parameters on isobutene selectivity. (0043) This example demonstrates a co-production process for isobutene and ETBE, where the TBA mixture is used as feed and the supplied fresh absolute ethanol is used as second feed by 0.562 ton/hr. The TBA concentration in the mixture comprising of TBA and 92% aqueous ethanol is 89.3 wt %. The total ethanol-to-TBA molar ratio in the first CD column is 0.25. Other unit parameters of the first CD column are given below. Column pressure is set at 4.5 kg/cm2 and total condenser is subcooled at 43.2° C. As reflux ratio and distillate to feed mass ratio are 3.4 and 0.76, the column size can be determined by these column parameters. Then, the calculated catalyst volume per tray is 0.197 m3. The calculated reaction temperature at the catalytic zone is 113.1-123.0° C. TBA conversion and isobutene selectivity are 99.2% and 89.7%, respectively
